Using-Procedure    

Spraying:–

This can be beneficial as part of the initial cleaning process after the carriage of Lube oils and Lube oil additives.  As soon as the tank in question has been checked empty by the attending surveyor, RXSOL-20-2001-210  should be sprayed over all surfaces which are safely reacheable.
 

Portable machines:–

After 45 minutes the butterworth machines should be operated for 3 x 20 minutes drops using warm 60o C, then the machines brought back to the top and a full hot wash 80 – 85 o C should be carried out for at least 6 hours.

Fixed machines:–

Wash ambient for 45 minutes followed by warm water for one cycle before increasing to hot (80oC) for 4 hours.

Injection:–

This can be carried out by injecting RXSOL-20-2001-210  into the butterworth system after the heater. A normal amount to use would be 100 – 150 liters during the initial washing cycle.  Water temperature should be 60o C during the injection period then brought up to 80 – 85 o C for the full washing period.

Re-circulation:–

Possibly the best result are achieved by re-circulating a solution of RXSOL-20-2001-210 after the initial rough washing of the tank.  A sufficient amount of fresh water to maintain good suction should be heated  to 60 o C and approximately 420 liters of RXSOL-20-2001-210  (2 drums) added for each 500 liters of fresh water.  The temperature of the mixture can be increased depending upon  the melting point if the product being cleaned.  The solution should be circulated for at least 4 hours and the butterworth machines  operated at maximum pressure in all areas of the tank  throughout this process.  If a number of tanks are to be circulated, then a substantial quantity of solution can be made so that transfers can be made without delay and any small amounts lost will not affect the operation.  Normally following transfer to another tank, 100 liters RXSOL-20-2001-210  is added for each 5000 liters of solution.  This is called “spiking”.
  

Following the re-circulation process, the tank must be hot butterworthed 80-85o C for at least 6 hours.
      *Use         a                 strainer                at               the                 pumpstack               when               circulating          any                        solution              RXSOL-20-2001-210 is recommended for local cleaning and degreasing and may be applied  by  brush,  hand  spray, immersion, soaking or any other conventional means. Apply concentrate RXSOL-20-2001-210 over  soiled  area  and wait for 20-30 minutes before rinsing off with water.
 

Soak Method:-

For heavy oil and soil Put parts to be cleaned into a bath of concentrate RXSOL-20-2001-210 and  for medium to light soiling use a solution of 10-30% RXSOL-20-2001-210 in water. Parts should be soaked for at least  30 minutes  before washing off with water.

Spray-Method:-

Spray concentrate  RXSOL-20-2001-210  over all soiled areas.  With in  15  and  30   minutes,  RXSOL-20-2001-210 starts   its function then rinse off by water hose. For stubborn deposits, agitation by scrubbing will  assist  the  cleaning operation .

Cargo Tank Cleaning after Mineral Oils

Direct injection method:–

Make  a   solution  of  RXSOL-20-2001-210  between   0.1  and  2.0%   i.e.   one   to    twenty    litres    per  ton   wash water.   Then      use     with     Tank     cleaning      machine ,    Best     results    are     obtained   when   water  is    heated  to  a     temperature      between          60  to  80°C.  Slops Should              be             Constantly              Stripped       from, tank.                                                   

Recirculation method / Ship's Rocking Mottion:– 

Make  soln.  Strength  with RXSOL-20-2001-210 between  0.5 –3 %  and  used  with  Tank Cleaning machines OR fill the tank to 20-30% volume with sea water and add the RXSOL-20-2001-210 up to full dose  . For better  results  heat  the solution  between 60 - 80°C.

NOTE : Dose rate and results will vary depending on amount of contamination.

Spot cleaning- RXSOL-20-2001-210  (concentrate) can be sprayed over surfaces and left  for  20 - 30 minutes  Finally wash down the tank surfaces with hot  water between 60°C and 80°C with  high  pressure   machine .   Keep stripping tank slops and transfer to holding tank/slop tank.Cleaning  of  theOil  side of  Lube  Oil Heat Exchangers  Cleaning  is  best  achieved  by the recirculation method using a heated 20% solution of RXSOL-20-2001-210.
1) First of all drain off any remaining oil from Heat Exchanger.
2) Connect the discharge side of a portable pump to the lower heat exchanger connection & the suction Side of the pump to the bottom outlet of a 200 litre drum.
3) Complete the circuit by connecting the upper connection on the heat exchanger to the top of the drum.
4) Maintain the bath temperature between 60-80 0 C throughout the cleaning operation.  If it is not possible to heat, the operation will need to be extended.
5) Use the pump to maintain circulation for 12 to 15 hours.  When the cleaning is completed, disconnect the lower heat exchanger connection and drain out the cleaning solution.
6) Connect a fresh water supply to the upper heat exchanger connection, and rinse until the water runs clean from the lower connection.                                                                                                                                                                                                                                                              When rinsing is complete, disconnect the water supply and thoroughly drain and dry the heat exchanger

Vegetable and Animal Oils (Cleaning Procedure)

 1. Butterworth the tank with seawater or freshwater with a temperature 20°C. above the melting point of the product to be cleaned. After sufficient pre-cleaning of at least 1.5 hours the temperature can be increased. Drying and Semi-drying ProductsThese are oxidising products and through reaction with oxygen they will dry and harden. Tank cleaning should be executed as soon as possible after discharge. High temperatures (e.g. cleaning or steaming) and heated cargoes in adjacent tanks should be avoided.
 2. Butterworth the tank with cold to warm seawater or freshwater.If the product has a higher melting point Butterworth the tank with seawater or freshwater with a temperature maximum 10°C above the melting point of the product. After sufficient pre-cleaning of at least 1.5 - 2 hours the temperature can be increased. Fatty Acids or  vegetable/animal oils with high free fatty acid contentsee the cleaning suggestion of Fatty Acids.
 3. If seawater was used in step 1 it is of utmost importance to flush/rinse the tank with freshwater before cleaning as per step 3 is continued.   
 4. (Final cleaning)Prepare the following solution (A) in freshwater (see table):
 

• Solution A(emulsification) 0. 4 % RXSOL-20-2046-210 Butterworth the tank with the prepared solution for 1, 5-2, 0 hours by recirculation. The necessary temperature can be achieved / maintained by means of heating coils, cargo heat exchanger or Butterworth heater. Depending on the amount of product residues the solution can be used for 1 to 4 tanks.On some vegetable/animal oils it is recommended to saponify additionally the product residues (see
  table): Therefore prepare one of the following solutions (B or C) in
  freshwater (see table):
   
• Solution B 0.4 % RXSOL-20-2046-210 plus 2.5% Potassium Hydroxide (KOH) or Sodium Hydroxide (NaOH)
   
• Solution C 0.4 % RXSOL-20-2046-210 plus 2 - 5% RXSOL AL 2005

 5. continued Butterworth the tank with the prepared solution for 1, 5-2, 0 hours by recirculation. The necessary temperature can be achieved /maintained by means of heating coil (service tank) cargo heat  exchanger or Butterworth heater.If RXSOL-20-2046-210 is used the  cleaning temperature should be 60-70°C If Sodium or Potassium Hydroxide is used the cleaning temperature should be 60.C.If RXSOL-20-2046-210 Marine is used the cleaning temperature can be 70-80°C. Depending on the amount of product residues the solution can be used for 1 to 3 tanks.
 6. Butterworth the tank 1 hour with hot seawater
 7. Rinse the tank with fresh water
 8. Inspect the tank; if white residues or a white film is present (calcium/magnesium soaps or carbonate) Butterworth the tank with one the following solution: 3-5% phosphoric acid and 0.4% RXSOL-20-2046-210 (stainless steel only); or 3-5% nitric acid and 0.4% RXSOL-20-2046-210 (stainless steel only); or 5-10% citric acid and 0,4% RXSOL-20-2046-210 (also suitable for Epoxy Coatings) or 2% RXSOL-16-1011-025 Marine and 0,4% RXSOL-20-2046-210 (also suitable for Epoxy Coatings) The cleaning temperature should be moderate (50°C.) Use heating coils not the Butterworth heater.
